I absolutely *HATE* a basketball goal mounted on the house above the garage door. No other single thing makes a house uglier.
But a pole in the yard like you show in the picture is so easy to
remove, that it doesn't bother me at all. Not only is it easy to
remove, but the ground beneath it will completely heal on its own, s no
harm, no foul (pardon the pun).
If you have a basketball goal mounted to the house, then I'd
heartily suggest you remove it and patch and paint the holes before showing, but I wouldn't worry too much about a pole in the yard.
